Description

technical field

[0001] The invention relates to the technical field of material microstructure and mechanical performance testing, in particular to an in-situ stretching device for X-ray testing. Background technique

[0002] In recent years, the concept of low-carbon development has become more and more popular, and lightweight engineering materials such as aluminum alloys and titanium alloys have attracted more and more attention. This type of material has the characteristics of high specific strength and corrosion resistance, and is widely used in aerospace, automotive lightweight, rail transit and other fields.

[0003] The microstructure of a material determines its macroscopic properties. Therefore, X-rays are usually used to characterize materials to evaluate their macroscopic properties. In order to further study the relationship between the performance and structure of materials, it is usually necessary to conduct in-situ tensile tests on materials. When performin...
